Original application filed December 14, 1922, Serial No. 606,851. Divided and this applicationfiled 7 December 6, 1923.

To all whom it may concern."

Be it known that I, Pn'rnUs ERICKSUN, a citizen of the United States, residmg at Chicago, in the county of Cook and State of Illinois, have invented a new and useful In. provement in Ball Retainers, of which the following is a specification.

This invention relates to ball retainers and the like, and is fully described in the following specification shown in the accompanying drawings, in which I Figure 1 is a frontelevation of a ball retainer for a thrust bearing with a set of balls assembled therein;

Fig. 2 is a reverse View of the retainer alone before the balls are assembled therein Fig. 3 is an enlarged section on the line 3 of Fig. 2; and

Fig. 4-is a section on the line 4 of Fig. 1.

This is a division of my application, Serial No. 606,851, filed December 14, 1922. which matured into Patent No. 1,481,000 dated January 15, 1924.

The ball retainer shown is adapted to be used on thrust bearings and has a flat annular ring 10 from which have been stamped cylindrical members which are made by a method described in the above named patent application. Each member consists of a substantially cylindrical portion 11 which is integral with the ring 10 and extends in one direction, and is bent back upon itself at 12 and has another and smaller cylindrical portion 13 which extendsthrough the cylindrical portion 11 as shown in Fig. 3.

The lower end of the portion 13 andthe connecting portion 12 are made slightly spherical so as to retain a ball 14 therein, but allowing the latter sufficient play that it may freely turn in the spherical portion as a socket. V

After the ball 14 is placed within this socket the retainer and ball are placed over a die 15, and a die 16 is forced down over the upper end of the cylindrical portion 13, forcing the latter about the ball as shown in Fig. 4, thereby squeezing the material Serial No. 678,883.

about the ball so that it can no longer be removed, but will still be free to turn within its socket.

It will be apparent that either the complete retainer with the balls assembled therein as shown in Fig. 1 or the retainer as shown in Fig. 2 before the balls are assembled therein is an article of manufacture and may be placed upon the market.

While I have shown and described but a single embodiment of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made first mentioned tubular portion.

doubled back to forma second sleeve within body provided with on opening therein, and body provided with an opening therein, and u continuciius tubular member secured to said a continuous tubular member integral with body and extending through said body and said body and extending through said body 10 beyond the opposite surfaces of said body, and beyond the opposite surfaces of said 5 said member having one end reduced to re body, said member having one end reduced ruin a hull therein. to retain a ball therein.
